As one of the most consistently brilliant puzzler series on mobile, you'd better believe that The Room is the real deal.

Across four games, Fireproof's locked box puzzlers have delighted, intrigued, challenged and spooked us in almost equal measure. And we've raved about each of them in turn.

Now there's a new entry in the series called The Room VR: A Dark Matter. It's been built exclusively for VR platforms, though, so this is one The Room game you won't be playing on your phone.

If that news has you feeling a little frustrated, or you just find yourself pining to escape the confines of a dark and dusty room for some reason (can't think why), here's a run down of the four preceding games and why you should play them. Those of you who haven't played all of them have the perfect opportunity to fill in the blanks, and you don't need to wear a silly hat to do so.

But for those of you that are fully versed on The Room series, there are other games on the App Store an Google Play Store that scratch the same itch. We're included five of the confounding suckers in our round-up of the best alternatives to The Room VR: A Dark Matter.
